Python Add-In Combobox Auto-Complete ?

Any good ideas on implementing an Auto-Complete function within a combobox??

I have three comboboxes:MAPSearch_item: Allows the user to select from a drop down, a layer to to execute the search againstMAPSearch_field: Allows the user to select from a drop down, the attribute field in the 'MAPSearch_item' to search withinMAPSearch_query: Allows the user to enter the value to search for in the selected field of the selected item. Once they hit enter, if the 'search value' is found, a select_analysis is executed and a feature class is added to the MXD containing the selected features.

To prevent users from misspelling a search value which would result in an error being raised, I'd like the 'MAPSearch_query' combobox to try and autocomplete the search term as they type it into the combobox. Any nifty ideas here?

Discovered a quazi-solution to this. It turns out that when a combobox is populated with values, if you hit the drop-down and then click inside the combobox to type in a value, the drop down remains displayed and will jump to exact value matches when you type them.

Not really an auto-complete like I wanted, but an interesting discovery nonetheless.

Still, what I want to try to implement is a way for the combobox to suggest values as you type, similar to the way google suggests search queries as you type them into google's searchbox.
